All supported architectures
Two Denial of Service vulnerabilities have been discovered in MySQL.
MySQL is a popular multi-threaded, multi-user SQL server.
mu-b discovered a NULL pointer dereference in item_cmpfunc.cc when
processing certain types of SQL requests. Sec Consult also discovered
another NULL pointer dereference when sorting certain types of queries
on the database metadata.
In both cases, a remote attacker could send a specially crafted SQL
request to the server, possibly resulting in a server crash. Note that
the attacker needs the ability to execute SELECT queries.
There is no known workaround at this time.
All MySQL users should upgrade to the latest version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-db/mysql-5.0.38"
